A. D. HATTON -fifu mmfi wflk J/ AT NEY Patented Jan. 30, 1951 UNITED STATES FATENT OFFICE ROTARY TEDDER FOR PEANUT HAR T R This invention relates to farming, and more particularly to the gathering of vines on which peanuts are growing, removing the dirt therefrom, and depositing them in a row or on a conveyor or support for subsequent handling.

Peanut diggers and shakers have been widely used heretofore but these have-oftentimes been complex in construction and not easily adapted for use with conventional farm machinery such as a tractor. Furthermore, handling of the vines after removal from the ground has often been complicated by the vines being caught in the drive mechanism for the shaker and by the need for replacement of the parts thereof, which has often involved a relatively expensive undertaking.

It is an object of the present invention to provide a peanut shaker which may be easily employed with a conventional tractor and which is adapted to engage the vines on the ground and move them overa plurality of guides as a result of which they are shaken and dirt adhering thereto largely removed and the vines deposited in a row behind the machine or on a conveyor or support provided therefor.

A further object of the invention is the provision of a peanut shaker in which novel means are provided for engaging and guiding the vines as they are shaken in order to remove foreign matter therefrom.

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Fig. 1 is a side elevation of a peanut shaker constructed in accordance with the present invention and illustratin the method by which it is attached to and used with a conventional tractor;

Fig. 2, a top plan view of the device shown in Fig. 1;

Fig. 3, a detail of a portion of one of the lateral bars showing the fingers for engagement with the vines attached thereto; end,

Fig. 4, a slightly enlarged section on the line 4-4 of Fig. 2.

Referring to the drawings, a tractor is shown having a. rear differential connected to a rear axle II of the tractor to which wheels [2 are attached. Positioned above the differential housing is a conventional power take off 13 having a control lever 14. A seat l5 and a steering wheel it are provided for use by the operator.

For supporting the peanut shaking mechanism which'is an embodiment of the present invention, a pair of box or channel members I! comprising the side members of a main frame are provided which rest at their forward portion on the housing of the axle H of the tractor and are secured. thereto by suitable means such as U bolts I8. The U bolts are fastened to the members H and extend around the lower portion of the housing of the axle H. A member l9 extends between the forward extremities of the side members I! to provide a front for the frame and is connected thereto by welding or the like. A strap iron member 20 has its ends spaced apart substantially the width of drive shaft housing 2| of the tractor and connected to the member [9 with its central portion extending under the axle housing in order to provide additional support for the main frame.

A main drive axle 22 is supported on pillars 23 attached to the members ll substantially midway between the rear extremity of the members I1 and the axle ll of the tractor. The axle 22 has a differential joint 24 from which a universal joint 25 extends and is connected to a universal joint 26 extending from the power take-off I? of the tractor by a rod 27. The axle 22 is provided with sprockets 28 at its extremities around which an endless drive chain 29 is adapted to be driven.

Attached to the under side of the rear extremity of the box member I! are bearings 30 in which an axle 3| is carried. The axle 3| extends beyond the side members I'! and has sprockets 32 for engagement with the chain 29 in order that power may be transmitted from the power take-off 13 of the tractor through the universal joint 26, rod 21, universal joint 25, differential 2t, axle 22, sprocket 28, and drive shaft 29 to the sprocket 32 in order to drive the axle 3 i The bearings 33 supporting the axle 3i are connected to an .end of box or chamiel members 3t c'dmprising the side members of a secondary frame. Thamembers 34 have bearings 36 at their other ends in which an axle 31 is journalled. Mounted between the inside of the members H and the'bearings 33 are relatively large sprockets 38 to which endless drive chains 39 are connected. The drive chains engage smaller sprockets AG on the axle 31 just within the side members I1.

Attached to the chains .39 are a plurality of substantially parallel transverse rod members 42, the rod members being provided at spaced intervals along the links of the chain and being attached thereto by suitable connectors passing through apertures {13 in the extremities of the rod members,

The rod members are provided to carry a plurality of fin ers 45 which are attached at spaced intervals thereto. The fingers .45 are comprised of flexible wire which is coiled around the members l2 and has its central section or bight G6 engaged with a fastening member ll attached to the member 52 which provides an abutment for the fingers and locates them on the rod members during assembly. The fingers #55 have offset end portions 48 in order that they may eificiently engage and lift the vines which have been loosened by a conventional plow or the like from the ground. The fingers are spaced substantially the same on alternate rod members, there being two sets of rod members having fingers of like spacing. The fingers of adjacent rod members are staggered relative to each other in order that maximum efficiency of lifting and moving the vines may be obtained.

The secondary frame comprising the channel members 34 and the axles 3| and 3'! may be pivoted about the axle 3| in order to adjust the height of the lowest portion of the secondary frame adjacent the axle 3? from the ground and also to permit the secondary frame to ride over obstacles such as rocks, logs, and the like. In order to support the lower portion of the secondary frame in various positions, chains 56 are looped over the channel members ll above the axle 3'? and are secured thereto by suitable means such as a connector 5|. In addition, a cable 52 is attached to the axle 3'! and extends to a conventional winch on the tractor operable at will by the driver.

Extending between the side members 34 of the secondary frame are a plurality of rails or bars 53, 54, and 55 which are substantially parallel to each other and to the axles 3| and 3? of the frame. The forward rail 53 has upwardly extending struts 56 connected thereto and the rails 5 and 55 have struts El and 58 of decreasing length in order to carry a plurality of spaced guide members 5% which extend substantially the length of the secondary frame, over the axles 3| and 37. These guide members have curved end portions as for guiding the vines off the device after they have traveled the length there- In order to protect the drive chain 39 from interference with vines and the like, a band of sheet material 62 of metal or the like surrounds the chain. It is supported by means of a plurality of spaced connecting members 63 which extend across the band on its outer side which are carried by connections to the side members 34 of the secondary frame.

A vine retaining and guiding side member 54 which extends the length of the secondary frame member and along the upper surface of the guard 62 is attached to the upper and outer portion of the guard in order to retain the vines within the shaking mechanism and to prevent their falling off the sides thereof.

In order to distribute the vines in a row at the rear of the shaker and to further agitate them, rods 66 are provided which are attached to the rear portion of the side members ll. These curve slightly inwardly toward the center of the device and have fingers or arms 67 which curve inwardly and downwardly in order to guide the vines as they move off the rear of the device.

In operation the tractor is attached to the peanut shaker which is the subject of this invention, the drive mechanism for the axles engaged, and the height of the lower portion of the device adjusted by means of the chain and/or the cable to the winch. The tractor is driven along the rows of the peanuts, a plow (not shown) loosening the vines initially from the ground. The

4 vines are picked up by the fingers 55 as the chains 39 are moved around the sprockets by means of the power train; the vines are lifted from the ground by the fingers and are carried rearwardly over the upper part of the device, the members 59 assisting the fingers and the rods 52 in supporting the vines on the upper portion of the device. As the vines are thus moved, the drive chain being loosely adjusted to permit agitation, they are shaken and aired, thus promoting the dislodgment therefrom of particles of foreign matter, including dirt or the like, which may drop down between the fingers and the allied parts of the device onto the ground beneath. The vines are deposited in a windrow at the rear of the shaker being guided by the fingers 61; if preferred a suitable receptacle Or other mechanism may follow the peanut shaker to receive the shaken vines.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawings and described in the specification but only as indicated in the appended claims.
